sPEoIFrcArIoN forming part @rimettere Patent-No. evzseaeatsd :my e;190i.` d l f Application ledNovemb'erl, 1900. `Serial No. 36,548.y `(Noniodlf) f To all whom, it may cortccrwrY Be it 'known that 1 GEORGE B,KINSLER,a citizen of the United States of America, residing at Hartford,inthe countyof Hartford and State of Connecticut, have invented new anduseful Improvements in' Universal .l'oints,*of

which the followingisa'specication. j

4 This invention relates to the construction of universal joints, theobject beingto provide animprovedarticle of this class which is adaptedto-beused between parts of shaft-l ing and in other devices wh: we agreater al1.-V gieV of incline is desired between the jointconnectedparts than has heretofore been attaiuable,'and, furthermore, to providea joint of this class in .which the'torsionalstrain between the partslthereof at all'points inthe movements et the same is equal; and theinvention consists in the peculiar construction and arrangement of the4parts ofthe device,A

all as hereinafter described and more pari toothed wrench for turningthem, or, if preticularlypoiuted out in ythe claims;

In the drawings forming part of' this-speciication, Figure 1 isasidedalevation showing' mty-improved universal joint applied to anduniting two sections of shaftingor Inetal bars.

Fig. 2 isa longitudinal .section of the parts i,

shown in Fig'.` l. Fig. 3 is a transverse section on linel3-3, Fig. -Y

Referring to thefdrawings, 'A A -indicate two pieces ot"v metal bars orchatting, eachofV which has two parallel ball-engaged arms projectingfrom one end thereof, whose outer vsides-are preferably in,` thel planeroffthe sur' 4face of said shaft parts and'whose inner walls arepa'rallel,-thu `s providing'a suitable spacebetween said arms for theintroduction of ballbearing devices, .as below described. Eachof said'four arms 3 has a nuti t'ted therein which is adjustable toward and fromI Said nuts have sockets in their outer ends to receive a ferred, theymay be slotted for a screw-driver.. Each of said nuts has yin its innerend a semispherical ball-recess;A Abad-engaging metal t ,block A5, ofsuitable dimensions to enterfreely between the extremities of said fourarms', has'semispherical` recesses in its side walls opposite the likerecesses in said nuts, and when said block is so placed, with a fball 6inten posed, `as shown in Fig. .3, betweenjeach of said nutsand theadjoining side of said block and'each nut screwed upito proper contactthe said two pairsfoi armsS is completed. i

'Itwill be noted by referringftofFigB that when' the blocl 5 isimposition betweenthe arms 3 of the shaft-section said block is ofslightly'smaller dimensionl than the area in-6o closed'by said arms. Theobject ot this constructionis to leavea little'roomiforthe'adjustinentof the-'nutse'toward the side -of said-:block to take up the'wear,either oftheA balls or tliesockets in which they'rcst, should 65litbecome necessary todo so. v

fflA great advantage in making "a joint as vabove described lies in thefact. that lthe block 5, theV balls 6, and the screws' Il may allbe'hardened, andffurthermore, any`- one of 7o '-the' balls or screws mayeasily be removed and. replaced without disturbing the othersfFurthermore', the balls, which` are, inetect, loose spherical beariu gsfor the shaftsections to swing on, permitsaidfsections to be moved 75freely in any 'direction of 'inclination oneto .the other withinvthelimits ozthe construeA tion without receivingany increase of eiort.

' -in-eecting the rotation of" said sections.

` Having thus described my'invention, what 8o 4I.. cla'i`m, and desiretosecure by Letters Pat-j i ent oi the United States, is-e 1; A universaljoint comprising two'shaft sections, two oppositely-located'arms on eachof the sections, aloose block located between 8 5 the-ends ot said arms,balls' interposed between said arms and said block and supported partlyin each, whereby said balls mayv serve as movable bearings for saidshaft-sections, and together with said block as inter- 9o locking meanstherefor, substantiallyl as described.

2. A universal joint comprising two shaftsections, twooppositely-located arms on each of said sections, a screw inthe end ofeach 95 armathe axis of which screws are at right angles to the axis ofthe shaft-sections, a ballrecess inV the end of said screws, a ball-re#ceiving block located between the said arms,

ballsrecesses in said bloclrfopposite the ends wewithitsballtheoperative connection between 55i of said screws, andballslying partly in the" recesses in said screws and partly in those ind said shaft'parts, a ball-engaging block intersaid block, substantiallyas`described.

3. A universal joint comprising two shaftsections, twooppositely-located arms on each of said sections, a ball-receiving block1ocated between the armssof the latter and hav ing ball-recessestherein, balls in saidrecesses, and means in said arms for holding saidballs in the recesses in the block, in the .saine plane whereby saidballs may serve as pivetal points for the latter, and as interlockingmeans between said shaft-sections, substantially as described.

l 4. A ball-bearing connection between vparte of shafting'or'similarstructural elements comprisingr two ball-engaging arms on each ofmediate of said arms, and a bearing-ball in.

termediate of each of said arms and the adjoining sid'e ofsaidblock,substantally as described. f

5. A ball-bearing connection between parts of shaftin'g or similarstructural elements, comprising two ball-engaging arms on each of saidshaft parts, a ball-engaging block in termediate of said arms, and abearing-ball intermediate of each of said. arms and the adjoining sideof said block,l and means for adjusting the contact pressure of saidballengaging parts thereagainst, substantially as described. 1
